Crews Complete Duct Bank Installation on 1st Avenue South

Seattle City Light crews recently installed an electrical duct bank on 1st Avenue South, between South Royal Brougham Way and Railroad Way South. Crews excavated on 1st Avenue South to install the new electrical duct bank. Traffic was detoured to the outside lanes during construction.

The completion of this project will aid in replacing aging electrical infrastructure and increasing electrical reliability for the SODO and Pioneer Square areas.

City Light thanks its customers for their patience during the successful completion of this project.

Crews to Install Electrical Duct Bank on 1st Avenue South

In early February 2018, Seattle City Light crews will be working along 1st Avenue South, between South Royal Brougham Way and Railroad Way South to install a new electrical duct bank. This work is needed to upgrade aging electrical infrastructure in the SODO neighborhood.

This project is set up in two stages:

Stage 1: Crews will begin working in the center two lanes on 1st Avenue South. Traffic will be detoured to the outside lanes going north and south.

Stage 2: Crews will then transition to the west side of 1st Avenue South, occupying both southbound lanes for the the duct bank installation. Southbound traffic will merge with the northbound lanes on 1st Avenue South.

Parking will be restricted on both sides of 1st Avenue South for truck staging and equipment storage. Work will not occur two hours before and after major Pioneer Square/South of Downtown (SODO) events.

Daily work hours are from Mondays through Fridays, 9 a.m. to 3 p.m., and weekends from 9 a.m. to 6 p.m.
